I have a SBS 2003 server on a clients site. I have just purchased a completely new 2008 Server R2 due to them not using the exchange function on their old SBS 2003 server. I am able to add the 2008 server to the domain and it is now functioning as a secondary domain controller.
What I want to do is completely remove the SBS 2003 server from the clients current site. However, when I tried to DC Promo the sbs server it tells me it is unable to perform this step. Is it possible to decommission the sbs 2003 which demands to be the primary controller?
